Just read the review!! Garsh!!
-This improve ran out of steam after about a minute. After that it just sortof sank to the back of my mind.
-The bassline got rather annoying after a while, as it seemed to just be octaves playing the same descending pattern for the entire song.
-The quality itself wasn't very good, but that's hardly your fault. Look into getting a keyboard that you can plug into the computer if you plan to keep doing these improvs. It would improve the general enjoyability a lot if the sound was better.
-There seemed to be parts where you were hugging the chords too much, but there were definetly tons of places where you seemed to be doing everything but hugging to chords, so kudos.
Consider looking into other keys than C Minor. As awesome as C Minor is (I love it too, it's just such a great key...) you should try the other ones too. Give F Minor a try too, I rather like it.
Keep it up. This is a great improv, better than i can manage (so far...) and it reeks of potential. Now i'm going to go check out your other stuff. Best of luck.
